Can you ID these eggs? Pics included

[Los]

Thanks in advance for your help with this. Today, after a water change on Sunday, I found an egg mass measuring approx. 3" x 1" spread out like a strand of spaghetti in a rough zig-zag pattern. The egg mass is about 18" from the bottom and right in the corner. The main coral underneath there is a soft colt / leather (not sure which). Each egg (and I'm assuming these are eggs) are about 1mm and they move and shift as the current washes by them. Here are the pics:

Here's a close up:

What do you think these are?

My large Cerith snail leaves a trail like that sometimes. When I try to clean it up if comes off in long, stringy, mucus-like strands.

HTH,
